Friday, February 02, 2024

Composite decking is a great way to make your outdoor living area both beautiful and functional. If you’re thinking about laying composite decking on your deck or patio, you may be wondering if it’s possible to lay composite decking boards over concrete. Read on to find out why it’s possible to lay composite decking over concrete decking, as well as some tips on how to install it properly.

Can You Install Composite Decking Over Concrete?

Yes, you can lay composite decking over concrete. Composite decking boards are strong and durable and will last a long time. So it works best on concrete decking and other hard surfaces.

Unlike materials such as gravel or sand, concrete is a more stable option for composite decking. Laying a deck directly on grass or dirt is not a good idea. Laying decking over concrete not only makes it a more stable surface, it can also have the following advantages:

Faster Installation

If a solid foundation is already in place, the construction time is cut in half. This is because there is no need to pour or install the base before installing composite decking.

Hiding Old Concrete

If the concrete on your decking is cracked, faded, or worn, you don’t have to worry about removing it all and laying down new concrete. Instead, save time and money by covering your deck with stylish, durable composite wood decking.

Give Your Patio a New Look

Composite wood decking is a great way to update an outdoor area or increase the resale value of your home. While concrete decking is useful, it doesn’t have the style, character, and ease of maintenance that composite decking does.

Composite Decking is Easy to Maintain

No More Weeds

What Do I Need to Lay Composite Decking Over Concrete?

To lay decking over concrete, you will need a few tools. If you plan and organize well before you start, it is possible to complete the installation faster and easier.

The following tools are needed to lay composite wood decking over concrete decking:

A Flat Surface

If you want to lay composite decking over concrete, you should have a solid, flat surface. You can use it even if the decking has cracks or is not quite level. You have the option of purchasing a self-leveling concrete repair product. Apply the product to the cracked or uneven decking, allow it to dry and set, and then you can lay composite wood decking normally.

Saw

Depending on the shape and size of the concrete decking, you may need to cut the composite decking boards. You can use common carpentry tools such as chop saws, table saws, circular saws, or jigsaws. Wear safety glasses and a mask over your mouth and eyes when using a saw to cut composite wood decking.

180-grit Sandpaper

You may need to use sandpaper to sand the composite wood decking to fit certain parts of the decking. Use at least 180 grit sandpaper to smooth the cut surfaces before applying the waterproof sealer.

Waterproofing Sealant

COOWIN composite decking is durable and will not stain, warp, crack, or develop other common decking problems. If you need to cut your composite wood decking, you should sand the cut edges and then seal the cut deck with a waterproof sealer. Thanks to the sealing treatment, wind, rain, and water will not be able to damage the edges of the deck.

How Do I Lay Composite Decking Over Concrete Decking?

One of the benefits of composite decking is that it is easy to install yourself. There is no need to spend money or time hiring a professional to lay a new crossing. You can build composite decking yourself and take care of the entire process. As long as you install the installation guide provided by the manufacturer of composite decking, you can excel at your deck installation project and be satisfied with it.

Picking the Right Composite Decking Boards

Picking the right decking material for your outdoor deck is important for a smooth installation. Keep the following points in mind when choosing a new deck:

  • Budget: How much can you spend on the entire project? Don’t forget to add the cost of regular maintenance to your calculations. Composite decking doesn’t require much maintenance, making it a very inexpensive way to build a flower girl.
  • Maintenance: Choose a decking material that suits your lifestyle. If you don’t have the time or skills to replace, paint, or refinish your deck on a regular basis. Then you’re better off picking a material for your deck that won’t fade, warp, or crack. For example, the low-maintenance and durable composite decking material.
  • Design style: A backyard allows you to show off your style or add a little extra color to your home. COOWIN composite decking comes in a variety of colors and shapes, and you can even customize any color to meet your needs.
  • Installation process: If you want to do the installation yourself, choose a deck trim that snaps into place.
  • Environmentally friendly: If you choose durable and recyclable composite decking, you’re doing your part to protect the environment.

Ensure Safety

To keep yourself safe when laying your new composite decking, make sure you have the right clothes and tools, such as:

  • Gloves: If you need to cut the decking, heavy-duty work gloves with a good grip will prevent your hands from getting cut.
  • Goggles: Wear goggles when using any saw. Goggles or a helmet will protect your eyes if something is flying around.
  • Long sleeves: If you are cutting composite decking boards, make sure your sleeves are away from the saw. Long sleeves will protect your skin from bug bites and sunburn.
  • Sunscreen: To prevent your skin from burning while working outdoors, be sure to apply sunscreen before you start laying decking on concrete.
  • Respiratory protection: Wear respiratory protection if you’re going to be using a saw. For example, wear a mask over your mouth and nose so you don’t inhale small pieces of particles.

Prepare the Surface

  • Prepare the surface for laying concrete decking before you start laying composite decking.
  • Remove any trash or furniture from the concrete decking.
  • Clear the patio so that there is an open area available for work.
  • If needed, clean the concrete decking with a hose or pressure wash and then let it dry.
  • After getting the area ready, wait for a dry and sunny day before laying composite decking boards.

Measuring Dimensions

How many composite decking boards you will need depends on how large the concrete patio you are covering is. Measuring will also give you an idea of whether you need to cut and shape the decking boards to fit in areas that are in the way or uneven.

Once you’ve taken your measurements, write down the dimensions of your concrete deck in square feet. Check this number against the dimensions of the deck you picked to get the correct calculation. It is recommended that you purchase extra composite decking boards in case you break them while cutting.

Placing and Installing the Deck

To avoid climate change making the deck expand or contract. When you receive the composite decking boards, you need to let it sit for about a week. Once the composite decking has acclimatized to the temperatures in your area, you can proceed with the installation of the deck. Here are some tips on how to lay composite decking over concrete:

  • Make a plan: When laying a deck with a designed pattern, don’t forget to pay attention to the attachment of the deck boards. To make it easier, you can place all the composite decking boards on the concrete deck according to the design you want to use before laying. You can rearrange the decking boards if needed. It also reduces the risk of mixing them up when laying if the deck is already in place. If you plan to use a very complex design or pattern, it may be necessary to draw the layout of the decking boards on paper before you begin.
  • Laying from the outside in: When laying composite decking, start on the outside and work your way to the center.
  • Laying the decking: Laying and fixing composite decking is now easy. When laying composite decking material over concrete, it is sufficient to install the composite decking according to the installation instructions provided by the manufacturer.

Cutting Composite Decking if Necessary

Can I lay decking over the concrete patio? Yes, but you may need to cut or trim new deck boards to fit the existing space. Don’t worry if your concrete deck is an odd shape or size, or if you have to work around something that can’t be moved. Cutting and placing deck boards is easy if you know what to do.

  • Point the end you plan to cut toward your house or other structural wall.
  • Place the deck board in the correct position and mark where you need to cut with a line. Mark the deck board with white chalk so you can quickly erase the lines if needed.
  • Use a saw to carefully cut the deck along the drawn lines.
  • Place the deck board over the area to make sure the cuts are made correctly and everything is aligned. Do not fasten with snaps or screws.
  • You can use sandpaper to smooth the cut surface of the deck board.
  • Seal the edges of the cut with a waterproof sealer made for composite decking and allow it to dry.
  • Secure the freshly cut deck boards with snaps and keep doing this until the deck is full.

Installation of Trim

Laying the trim around the composite decking is the last thing that needs to be done during the building process. There are several reasons why the trim should be installed:

  • To add the “finishing touch” to the deck.
  • So people don’t trip over the edge of the deck.
  • To draw attention to or match the style, color, or design of your chosen composite decking.

You can purchase three types of trim from COOWIN: straight trim, inside corner trim, and outside corner trim. These trims come in a variety of different colors, so you can choose the color that best matches the rest of your deck.
